[PATCH] hostap: allow flashing firmware
Host AP driver has code to support writing firmware to non-volatile
memory, a.k.a. flash. This code has been extensively tested when Host
AP was a standalone driver.
Add a configuration option to the kernel to allow enabling this
functionality. Improve the description of the RAM download option.
Mention cards that require it. Remove obsolete scary comment.
